How many players drafted outside of the top five rounds ever make it to the bigs? Roth stayed because he knew he could get a good education and make a lot of money even if he didn't make it in the pros.

there are plenty of guys not drafted in the top 5 rounds in the bigs right now, there are 50ish rounds in the draft, to go in the top 5-10 rounds puts you in the top 10-20% of all prospects, just go to the braves roster and look at when most of those guys were drafted.
